The eight queens issue is an ancient and famous issue and is a typical case of backtracking algorithms. This problem was raised by Max #183, an international chess player, who proposed in 1848 that eight queens should be placed on 8x8 chess so that they could not attack each other, that is to say, neither of the two queens can be in the same row, column, or diagonal line. It can match the pattern like Haskell and Prolog, Create logic to push to rules, describe the question, and get the answer.

Php interview question 1. use PHP to print the time format of the previous day in the format of 22:21:21 (2 points) "u % j q! S $} 0 V8 ~ 4? #? Date ("Y-m-d H: I: s", strtotime ("-1 days ")); 2. differences between echo (), print (), and print_r () (3 points)Echo is a PHP statement, print and print_r are functions, and the statement does not return values. the function can return values (even if it is not used)Print () can only print values of simple type variables (such as int and string)

the source MAC address is its own MAC address. SWA when the frame is received, the mapping of the source MAC address and the receive port is added to the MAC address table. By default, the X7 series switch learns a MAC Address table entry that has an aging time of 300 seconds. If the data frame sent by host A is received again within the aging time, the aging time of the MAC address of host a saved in SWA and the G0/0/1 mapping will be refreshed. The

At the same time, since the weights are integers from 1 to 100

(generator polynomial): When the CRC test, the sender and receiver need to agree with a divisor, that is, to generate a polynomial, generally written as g (x). The highest and lowest bits of the generated polynomial must be 1. The common CRC code generation polynomial is:Crc8=x8+x5+x4+1Crc-ccitt=x16+x12+x5+1Crc16=x16+x15+x5+1Crc12=x12+x11+x3+x2+1Crc32=x32+x26+x23+x22+x16+x12+x11+x10+x8+x7+x5+x4+x2+x1+1Each generated polynomial can correspond to a cod

HDU4149 Magic Potion (bitwise Operation) Question: returns the result of an exclusive or operation between x1, x2, x3, x4, x5, x6, x7, and x8 and a value of m ~ Sum of the sum of x8 and the result sum after m's XOR operation, evaluate m. Ideas: According to the bit operation characteristics, since the maximum m is 32 bits, we can infer from the first bit, using x> I 1 to get the value of the right number of the I-1 bit. Assume that the first digit f

You are given a strange scale (see the figure below), and you are wondering how to balance this scale. after several attempts, you have discovered the way to balance it -- you need to put different numbers on different squares while satisfying the following two equations: X1 *4 + X2 *3 + X3 *2 + X4 = X5 + X6 *2 + X7 *3 + X8 *4 Y1 *4 + Y2 *3 + Y3 *2 + Y4 = Y5 + Y6 *2 + Y7 *3 + Y8 *4 How many ways can you balance this strange scale with the give
